Wilderness of Sin?

Linguists and philologists from the University of Baskerville assure us that this sign is in an
ancient Midian script, and means something like, roughly rendered, "Go home Israelites".
In spite of serious rusting, the iron legs of the sign can be carbon-dated to about
the middle of the Lower Upper Bronze IIII period, putting the erection
of the sign around the sixth century BC, just when, according to eminent
archeologists, the Exodus account was written. (Google Earth photo)
